np.fromfile() has a sep= keyword argument:

Separator between items if file is a text file. Empty (“”) separator means the file should be treated as binary. Spaces (” ”) in the separator match zero or more whitespace characters. A separator consisting only of spaces must match at least one whitespace.

The default value of sep="" means that np.fromfile() tries to read it as a binary file rather than a space-separated text file, so you get nonsense values back. If you use np.fromfile('markers.txt', sep=" ") you will get the result you are looking for.

However, as others have pointed out, np.loadtxt() is the preferred way to convert text files to numpy arrays, and unless the file needs to be human-readable it is usually better to use binary formats instead (e.g. np.load()/np.save()).

If you just want to temporarily change to another environment, use

source activate environment-name

(you can create environment-name with `conda create)

To change permanently, there is no method except creating a startup script that runs the above code.

Typically it's best to just create new environments. However, if you really want to change the Python version in the default environment, you can do so as follows:

First, make sure you have the latest version of conda by running

conda update conda

Then run

conda install python=3.5

This will attempt to update all your packages in your root environment to Python 3 versions. If it is not possible (e.g., because some package is not built for Python 3.5), it will give you an error message indicating which package(s) caused the issue.

If you installed packages with pip, you'll have to reinstall them.

The other solutions do not work for chrome driver v83.

Instead, it works as follows, suppose there is only 1 opening tab:

driver.execute_script("window.open('');")
driver.switch_to.window(driver.window_handles[1])
driver.get("https://www.example.com")

If there are already more than 1 opening tabs, you should first get the index of the last newly-created tab and switch to the tab before calling the url (Credit to tylerl) :

driver.execute_script("window.open('');")
driver.switch_to.window(len(driver.window_handles)-1)
driver.get("https://www.example.com")

Its Simple use this command:

git push -f origin master

and it will get your work done

double value = 2.8032739273;
String formattedValue = value.toStringAsFixed(3);

Make sure you have DESERIALIZED objects like DATE/DATETIME etc. If you are directly sending JSON without deserializing it then it can cause this problem.

Enter with Administrator user. First, you must enable it http://www.ghacks.net/2014/11/12/how-to-enable-the-hidden-windows-10-administrator-account/

Install it from C:\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm-andoid.exe

And login with your user. It work for me.

The JWT aud (Audience) Claim

According to RFC 7519:

The "aud" (audience) claim identifies the recipients that the JWT is intended for. Each principal intended to process the JWT MUST identify itself with a value in the audience claim. If the principal processing the claim does not identify itself with a value in the "aud" claim when this claim is present, then the JWT MUST be rejected. In the general case, the "aud" value is an array of case- sensitive strings, each containing a StringOrURI value. In the special case when the JWT has one audience, the "aud" value MAY be a single case-sensitive string containing a StringOrURI value. The interpretation of audience values is generally application specific. Use of this claim is OPTIONAL.

The Audience (aud) claim as defined by the spec is generic, and is application specific. The intended use is to identify intended recipients of the token. What a recipient means is application specific. An audience value is either a list of strings, or it can be a single string if there is only one aud claim. The creator of the token does not enforce that aud is validated correctly, the responsibility is the recipient's to determine whether the token should be used.

Whatever the value is, when a recipient is validating the JWT and it wishes to validate that the token was intended to be used for its purposes, it MUST determine what value in aud identifies itself, and the token should only validate if the recipient's declared ID is present in the aud claim. It does not matter if this is a URL or some other application specific string. For example, if my system decides to identify itself in aud with the string: api3.app.com, then it should only accept the JWT if the aud claim contains api3.app.com in its list of audience values.

Of course, recipients may choose to disregard aud, so this is only useful if a recipient would like positive validation that the token was created for it specifically.

My interpretation based on the specification is that the aud claim is useful to create purpose-built JWTs that are only valid for certain purposes. For one system, this may mean you would like a token to be valid for some features but not for others. You could issue tokens that are restricted to only a certain "audience", while still using the same keys and validation algorithm.

Since in the typical case a JWT is generated by a trusted service, and used by other trusted systems (systems which do not want to use invalid tokens), these systems simply need to coordinate the values they will be using.

Of course, aud is completely optional and can be ignored if your use case doesn't warrant it. If you don't want to restrict tokens to being used by specific audiences, or none of your systems actually will validate the aud token, then it is useless.

Example: Access vs. Refresh Tokens

One contrived (yet simple) example I can think of is perhaps we want to use JWTs for access and refresh tokens without having to implement separate encryption keys and algorithms, but simply want to ensure that access tokens will not validate as refresh tokens, or vice-versa.

By using aud, we can specify a claim of refresh for refresh tokens and a claim of access for access tokens upon creating these tokens. When a request is made to get a new access token from a refresh token, we need to validate that the refresh token was a genuine refresh token. The aud validation as described above will tell us whether the token was actually a valid refresh token by looking specifically for a claim of refresh in aud.

OAuth Client ID vs. JWT aud Claim

The OAuth Client ID is completely unrelated, and has no direct correlation to JWT aud claims. From the perspective of OAuth, the tokens are opaque objects.

The application which accepts these tokens is responsible for parsing and validating the meaning of these tokens. I don't see much value in specifying OAuth Client ID within a JWT aud claim.

In Laravel 6.x

// Retrieve a piece of data from the session...
$value = session('key');

// Specifying a default value...
$value = session('key', 'default');

// Store a piece of data in the session...
session(['key' => 'value']);

https://laravel.com/docs/6.x/session

After experiencing issues with sites breaking on Edge when using High Contrast Mode, I came across the following work by Jeff Clayton:

https://browserstrangeness.github.io/css_hacks.html

It's a crazy, weird media query, but those are easier to use in Sass:

@media screen and (min-width:0\0) and (min-resolution:+72dpi), \0screen\,screen\9 {
   .selector { rule: value };
}

This targets IE versions expect for IE8.

Or you can use:

@media screen\0 {
  .selector { rule: value };
}

Which targets IE8-11, but also triggers FireFox 1.x (which for my use case, doesn't matter).

Right now I'm testing with print support, and this seems to be working okay:

@media all\0 {
  .selector { rule: value };
}

To accomplish this, add 2 CSS properties on the <body> element.

body {
   height: 100%;
   overflow-y: hidden;
}

These days there are many news websites which require users to create an account. Typically they will give full access to the page for about a second, and then they show a pop-up, and stop users from scrolling down.

you may also want to npm remove gulp-sass and re-install gulp-sass if you've switched node versions.

In Oracle, you can simply subtract two dates and get the difference in days. Also note that unlike SQL Server or MySQL, in Oracle you cannot perform a select statement without a from clause. One way around this is to use the builtin dummy table, dual:

SELECT TO_DATE('2000-01-02', 'YYYY-MM-DD') -  
       TO_DATE('2000-01-01', 'YYYY-MM-DD') AS DateDiff
FROM   dual

Tip: Browse the container documentation forums, like the Docker Forum.

Here's a solution for debian & ubuntu, add the following to your Dockerfile:

RUN apt-get update && apt-get install -y locales && rm -rf /var/lib/apt/lists/* \
    && localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8
ENV LANG en_US.UTF-8

This work for me in Laravel 7.x in 3 simple steps using a middleware:

1) Generate the middleware with command php artisan make:middleware ForceSSL

Middleware

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\App;

class ForceSSL
{
    public function handle($request, Closure $next)
    {
        if (!$request->secure() && App::environment() === 'production') {
            return redirect()->secure($request->getRequestUri());
        }

        return $next($request);
    }
}

2) Register the middleware in routeMiddleware inside Kernel file

Kernel

protected $routeMiddleware = [
    //...
    'ssl' => \App\Http\Middleware\ForceSSL::class,
];

3) Use it in your routes

Routes

Route::middleware('ssl')->group(function() {
    // All your routes here

});

.HTACCESS Method

If you prefer to use an .htaccess file, you can use the following code:

<IfModule mod_rewrite.c>
    RewriteEngine On 
    RewriteCond %{SERVER_PORT} 80 
    RewriteRule ^(.*)$ https://yourdomain.com/$1 [R,L]

It looks like your 'trainData' is a list of strings:

['-214' '-153' '-58' ..., '36' '191' '-37']

Change your 'trainData' to a numeric type.

 import numpy as np
 np.array(['1','2','3']).astype(np.float)

<init-param> will be used if you want to initialize some parameter for a particular servlet. When request come to servlet first its init method will be called then doGet/doPost whereas if you want to initialize some variable for whole application you will need to use <context-param> . Every servlet will have access to the context variable.

It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment to your bean.

@Autowired
private Environment environment;
....

this.environment.getActiveProfiles();

If you are using httpclient 4.2, then you need to write a small bit of extra code. I wanted to be able to customize both the "TLS enabled protocols" (e.g. TLSv1.1 specifically, and neither TLSv1 nor TLSv1.2) as well as the cipher suites.

public class CustomizedSSLSocketFactory
    extends SSLSocketFactory
{
    private String[] _tlsProtocols;
    private String[] _tlsCipherSuites;

    public CustomizedSSLSocketFactory(SSLContext sslContext,
                                      X509HostnameVerifier hostnameVerifier,
                                      String[] tlsProtocols,
                                      String[] cipherSuites)
    {
        super(sslContext, hostnameVerifier);

        if(null != tlsProtocols)
            _tlsProtocols = tlsProtocols;
        if(null != cipherSuites)
            _tlsCipherSuites = cipherSuites;
    }

    @Override
    protected void prepareSocket(SSLSocket socket)
    {
        // Enforce client-specified protocols or cipher suites
        if(null != _tlsProtocols)
            socket.setEnabledProtocols(_tlsProtocols);

        if(null != _tlsCipherSuites)
            socket.setEnabledCipherSuites(_tlsCipherSuites);
    }
}

Then:

    SSLContext sslContext = SSLContext.getInstance("TLS");

    sslContext.init(null, getTrustManagers(), new SecureRandom());

    // NOTE: not javax.net.SSLSocketFactory
    SSLSocketFactory sf = new CustomizedSSLSocketFactory(sslContext,
                                                         null,
                                                         [TLS protocols],
                                                         [TLS cipher suites]);

    Scheme httpsScheme = new Scheme("https", 443, sf);
    SchemeRegistry schemeRegistry = new SchemeRegistry();
    schemeRegistry.register(httpsScheme);

    ConnectionManager cm = new BasicClientConnectionManager(schemeRegistry);

    HttpClient client = new DefaultHttpClient(cmgr);
    ...

You may be able to do this with slightly less code, but I mostly copy/pasted from a custom component where it made sense to build-up the objects in the way shown above.

as per @cyberbikepunk answer pycharm supports Anaconda since pycharm5!

Have a look how easy is to add an environment:

Someone had gave good answers. I made another instruction clue step by step. First, open your studio and search. You can find the decompier is Fernflower.

Second, we can find it in the plugins directory.

/Applications/Android Studio.app/Contents/plugins/java-decompiler/lib/java-decompiler.jar

Third, run it, you will get the usage

java -cp "/Applications/Android Studio.app/Contents/plugins/java-decompiler/lib/java-decompiler.jar" org.jetbrains.java.decompiler.main.decompiler.ConsoleDecompiler

Usage: java -jar fernflower.jar [-<option>=<value>]* [<source>]+ <destination>
Example: java -jar fernflower.jar -dgs=true c:\my\source\ c:\my.jar d:\decompiled\

Finally, The studio's nest options for decompiler list as follows according IdeaDecompiler.kt

-hdc=0 -dgs=1 -rsy=1 -rbr=1 -lit=1 -nls=1 -mpm=60 -lac=1

IFernflowerPreferences.HIDE_DEFAULT_CONSTRUCTOR to "0",
        IFernflowerPreferences.DECOMPILE_GENERIC_SIGNATURES to "1",
        IFernflowerPreferences.REMOVE_SYNTHETIC to "1",
        IFernflowerPreferences.REMOVE_BRIDGE to "1",
        IFernflowerPreferences.LITERALS_AS_IS to "1",
        IFernflowerPreferences.NEW_LINE_SEPARATOR to "1",
        **IFernflowerPreferences.BANNER to BANNER,**
        IFernflowerPreferences.MAX_PROCESSING_METHOD to 60,
        **IFernflowerPreferences.INDENT_STRING to indent,**
        **IFernflowerPreferences.IGNORE_INVALID_BYTECODE to "1",**
        IFernflowerPreferences.VERIFY_ANONYMOUS_CLASSES to "1",
         **IFernflowerPreferences.UNIT_TEST_MODE to if (ApplicationManager.getApplication().isUnitTestMode) "1" else "0")**

I cant find the sutialbe option for the asterisk items.

Hope these steps will make the question clear.

This is the code Android uses to display notification icons:

// android_frameworks_base/packages/SystemUI/src/com/android/systemui/
//   statusbar/BaseStatusBar.java

if (entry.targetSdk >= Build.VERSION_CODES.LOLLIPOP) {
    entry.icon.setColorFilter(mContext.getResources().getColor(android.R.color.white));
} else {
    entry.icon.setColorFilter(null);
}

So you need to set the target sdk version to something <21 and the icons will stay colored. This is an ugly workaround but it does what it is expected to do. Anyway, I really suggest following Google's Design Guidelines: "Notification icons must be entirely white."

Here is how you can implement it:

If you are using Gradle/Android Studio to build your apps, use build.gradle:

defaultConfig {
    targetSdkVersion 20
}

Otherwise (Eclipse etc) use AndroidManifest.xml:

<uses-sdk android:minSdkVersion="..." android:targetSdkVersion="20" />

I'm using Linux where I had a symlink in my home folder pointing to a folder containing the Android Studio projects. Loading a project using the symlink failed, loading a project from the folder where the symlink is pointing to worked!

No problem. You're running your code under the debugger, and the debugger is telling you that it doesn't have debugging information for the system libraries.

If you really need that (usually for stack traces), you can download it from Microsoft's symbol servers, but for now you don't need to worry.

https://raw.githubusercontent.com/[USER-NAME]/[REPOSITORY-NAME]/[BRANCH-NAME]/[FILE-PATH]

Ex. https://raw.githubusercontent.com/vipinbihari/apana-result/master/index.php

Through this you would get the contents of an individual file as a row text. You can download that text with wget.

Use Not Like

where some_column NOT LIKE '%[^0-9]%'

Demo

declare @str varchar(50)='50'--'asdarew345'

select 1 where @str NOT LIKE '%[^0-9]%'

To be honest I like the OP's first way of actually starting it with a NULL value and then checking it with is.null (primarily because it is very simply and easy to understand). It maybe depends on the way people are used to coding but the Hadley seems to support the is.null way too:

From Hadley's book "Advanced-R" Chapter 6, Functions, p.84 (for the online version check here):

You can determine if an argument was supplied or not with the missing() function.

i <- function(a, b) {
  c(missing(a), missing(b))
}
i()
#> [1] TRUE TRUE
i(a = 1)
#> [1] FALSE  TRUE
i(b = 2)
#> [1]  TRUE FALSE
i(1, 2)
#> [1] FALSE FALSE

Sometimes you want to add a non-trivial default value, which might take several lines of code to compute. Instead of inserting that code in the function definition, you could use missing() to conditionally compute it if needed. However, this makes it hard to know which arguments are required and which are optional without carefully reading the documentation. Instead, I usually set the default value to NULL and use is.null() to check if the argument was supplied.

I normally use the HttpPostedFileBase parameter only in Mvc Controllers. When dealing with ApiControllers try checking the HttpContext.Current.Request.Files property for incoming files instead:

[HttpPost]
public string UploadFile()
{
    var file = HttpContext.Current.Request.Files.Count > 0 ?
        HttpContext.Current.Request.Files[0] : null;

    if (file != null && file.ContentLength > 0)
    {
        var fileName = Path.GetFileName(file.FileName);

        var path = Path.Combine(
            HttpContext.Current.Server.MapPath("~/uploads"),
            fileName
        );

        file.SaveAs(path);
    }

    return file != null ? "/uploads/" + file.FileName : null;
}

Try this one for diamond pattern in javascript

<head>
 <style>
    p{text-align:center;margin-left:20px;}
 </style>
</head>

<body>
   <h1>JavaScript patterns</h1>
   <p id="demo"></p>

<script>
  var x=function(n){
    document.write("<center>");

  var c="";
    for(var i=0; i<n; i++){
      c=c+"#";
      document.write(c);
      document.write("<br>");  
   }

    for(var k=n;k>0;k--){
      for(var j=0; j<(k-1); j++){
       document.write("#");
      } 
    document.write("<br>");
   }   
  }
     document.getElementById("demo").innerHTML = x(10);

</script>

I think onMouseEnter and onMouseLeave are the ways to go, but I don't see the need for an additional wrapper component. Here is how I implemented it:

var Link = React.createClass({
  getInitialState: function(){
    return {hover: false}
  },
  toggleHover: function(){
    this.setState({hover: !this.state.hover})
  },
  render: function() {
    var linkStyle;
    if (this.state.hover) {
      linkStyle = {backgroundColor: 'red'}
    } else {
      linkStyle = {backgroundColor: 'blue'}
    }
    return(
      <div>
        <a style={linkStyle} onMouseEnter={this.toggleHover} onMouseLeave={this.toggleHover}>Link</a>
      </div>
    )
}

You can then use the state of hover (true/false) to change the style of the link.

I found a solution on another thread that works - use the pull-left class:

 <a href="#" class="pull-left"><img src="/path/to/image.png"></a> 

Thanks to Michael in this thread:

Bootstrap - How to add a logo to navbar class?

In the new lodash release v4.0.0 _.pluck has removed in favor of _.map

Then you can use this:

_.map(users, 'id'); // [12, 14, 16, 18]

You can see in Github Changelog

I was having the same problem here. Found out that the problem was with an Advanced Property of the file. There is there an option with the name 'Compilation Action' (may be not with the exact words, I am translating - my VS is in Portuguese).

My Class1.cs file was there as "Content" and I just had to change it to "Compile" to make it work, and have the classes recognized by the others files in the same project.

Add above code in API gateway under GET-Integration Request> mapping section.

An utility method like the following can be used to solve this.

import (
  "os"
  "path/filepath"
  "log"
)

func ensureDir(fileName string) {
  dirName := filepath.Dir(fileName)
  if _, serr := os.Stat(dirName); serr != nil {
    merr := os.MkdirAll(dirName, os.ModePerm)
    if merr != nil {
        panic(merr)
    }
  }
}



func main() {
  _, cerr := os.Create("a/b/c/d.txt")
  if cerr != nil {
    log.Fatal("error creating a/b/c", cerr)
  }
  log.Println("created file in a sub-directory.")
}

You should definitely have a look at this answer of mine:

• Extracting table contents from a collection of PDF files

and also have a look at all the links included therein.

Tabula/TabulaPDF is currently the best table extraction tool that is available for PDF scraping.

If you've scrolled far enough to reach this answer, I wrote a library for equal spacing which supports Vertical/Horizontal, LTR/RTL, LinearLayout/GridLayout manager and Edge inclusion. Its basically a single file, so you can copy paste that file into your code.

I tried to support StaggeredGridLayout but span index returned by this layout is not reliable. I would be glad to hear any suggestion for that.

In my case I had inherited from the IdentityDbContext correctly (with my own custom types and key defined) but had inadvertantly removed the call to the base class's OnModelCreating:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    base.OnModelCreating(modelBuilder); // I had removed this
    /// Rest of on model creating here.
}

Which then fixed up my missing indexes from the identity classes and I could then generate migrations and enable migrations appropriately.

With Swift 5, according to your needs, you may choose one of the 6 following Playground codes in order to solve your problem.

#1. Using subscript(_:) subscript

let array = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L"]
let arraySlice = array[..<5]
//let arraySlice = array[0..<5] // also works
//let arraySlice = array[0...4] // also works
//let arraySlice = array[...4] // also works
let newArray = Array(arraySlice)
print(newArray) // prints: ["A", "B", "C", "D", "E"]

#2. Using prefix(_:) method

Complexity: O(1) if the collection conforms to RandomAccessCollection; otherwise, O(k), where k is the number of elements to select from the beginning of the collection.

let array = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L"]
let arraySlice = array.prefix(5)
let newArray = Array(arraySlice)
print(newArray) // prints: ["A", "B", "C", "D", "E"]

Apple states for prefix(_:):

If the maximum length exceeds the number of elements in the collection, the result contains all the elements in the collection.

#3. Using prefix(upTo:) method

Complexity: O(1)

let array = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L"]
let arraySlice = array.prefix(upTo: 5)
let newArray = Array(arraySlice)
print(newArray) // prints: ["A", "B", "C", "D", "E"]

Apple states for prefix(upTo:):

Using the prefix(upTo:) method is equivalent to using a partial half-open range as the collection's subscript. The subscript notation is preferred over prefix(upTo:).

#4. Using prefix(through:) method

let array = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L"]
let arraySlice = array.prefix(through: 4)
let newArray = Array(arraySlice)
print(newArray) // prints: ["A", "B", "C", "D", "E"]

#5. Using removeSubrange(_:) method

Complexity: O(n), where n is the length of the collection.

var array = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L"]
array.removeSubrange(5...)
print(array) // prints: ["A", "B", "C", "D", "E"]

#6. Using dropLast(_:) method

Complexity: O(1) if the collection conforms to RandomAccessCollection; otherwise, O(k), where k is the number of elements to drop.

let array = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L"]
let distance = array.distance(from: 5, to: array.endIndex)
let arraySlice = array.dropLast(distance)
let newArray = Array(arraySlice)
print(newArray) // prints: ["A", "B", "C", "D", "E"]

Object assign copies one or more source objects to the target object. So we could use Object.assign here.

Syntax: Object.assign(target, ...sources)

var obj  = {};_x000D_
_x000D_
Object.assign(obj, {"1":"aa", "2":"bb"})_x000D_
_x000D_
console.log(obj)

The other plus of using RecycleView is animation, it can be done in two lines of code

RecyclerView.ItemAnimator itemAnimator = new DefaultItemAnimator();
        recyclerView.setItemAnimator(itemAnimator);

But the widget is still raw, e.g you can't create header and footer.

var first_number = parseInt(document.getElementById("Text1").value);
var second_number = parseInt(document.getElementById("Text2").value);

// This is because your method .getElementById has the letter 's': .getElement**s**ById

If you are stuck with a machine where you don't have root access, then it is better to deal with a custom Python installation.

The Anaconda installation worked like a charm:

• Installing packages (SciPy.org)
• Anaconda Python/R Distribution - download

After installation,

[bash]$ /xxx/devTools/python/anaconda/bin/pip list --format=columns | grep numpy

numpy 1.13.3 numpydoc 0.7.0

This solution had worked for me:

I assume that you have installed nodemon globally. If it's done follow this steps:

open your .bash_profile file:

nano .bash_profile

past this to add a new alias in your bash profile:

alias nodemon='~/.npm-global/lib/node_modules/nodemon/bin/nodemon.js'

Now you can use nodemon command anywhere.

For me the problem was that I was passing Activity to the constructor, not Context

public Adapter(Activity activity, List<MediaItem> items, boolean can) {
    mItems = items;
    canEdit = can;
    mActivity = activity;
}

and using this activity to getDefaultSharedPreferences(), so I changed the Activity to Context and I was still calling the Adapter constructor with MainActivity.this

Why not:

onItemClick: function (event) {

    event.currentTarget.style.backgroundColor = '#ccc';

},

render: function() {
    return (
        <div>
            <ul>
                <li onClick={this.onItemClick}>Component 1</li>
            </ul>
        </div>
    );
}

And if you want to be more React-ive about it, you might want to set the selected item as state of its containing React component, then reference that state to determine the item's color within render:

onItemClick: function (event) {

    this.setState({ selectedItem: event.currentTarget.dataset.id });
    //where 'id' =  whatever suffix you give the data-* li attribute
},

render: function() {
    return (
        <div>
            <ul>
                <li onClick={this.onItemClick} data-id="1" className={this.state.selectedItem == 1 ? "on" : "off"}>Component 1</li>
                <li onClick={this.onItemClick} data-id="2" className={this.state.selectedItem == 2 ? "on" : "off"}>Component 2</li>
                <li onClick={this.onItemClick} data-id="3" className={this.state.selectedItem == 3 ? "on" : "off"}>Component 3</li>
            </ul>
        </div>
    );
},

You'd want to put those <li>s into a loop, and you need to make the li.on and li.off styles set your background-color.

Your inputs lack one important information of device dimension. Suppose now popular phone is 6 inch(the diagonal of the display), you will have following results

DPI: Dots per inch - number of dots(pixels) per segment(line) of 1 inch. DPI=Diagonal/Device size

Scaling Ratio= Real DPI/160. 160 is basic density (MHDPI)

DP: (Density-independent Pixel)=1/160 inch, think of it as a measurement unit

You can also use the .to_frame() method.

If it is a Series, I assume 'Gene' is already the index, and will remain the index after converting it to a DataFrame. The name argument of .to_frame() will name the column.

x = x.to_frame('count')

If you want them both as columns, you can reset the index:

x = x.to_frame('count').reset_index()

For checking the version of scikit-learn in shell script, if you have pip installed, you can try this command

pip freeze | grep scikit-learn
scikit-learn==0.17.1

Hope it helps!

Use ?? instead or {{ $usersType ?? '' }}

If you're working with localised strings, you might not be able to rely on the bold string always being at the end of the sentence. If this is the case then the following works well:

e.g. Query "blah" does not match any items

/* Create the search query part of the text, e.g. "blah". 
   The variable 'text' is just the value entered by  the user. */
let searchQuery = "\"\(text)\""

/* Put the search text into the message */
let message = "Query \(searchQuery). does not match any items"

/* Find the position of the search string. Cast to NSString as we want
   range to be of type NSRange, not Swift's Range<Index> */
let range = (message as NSString).rangeOfString(searchQuery)

/* Make the text at the given range bold. Rather than hard-coding a text size,
   Use the text size configured in Interface Builder. */
let attributedString = NSMutableAttributedString(string: message)
attributedString.addAttribute(NSFontAttributeName, value: UIFont.boldSystemFontOfSize(label.font.pointSize), range: range)

/* Put the text in a label */
label.attributedText = attributedString

i had the same problem, i added the following lines in build.gradle

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }

        maven {
            url 'http://dl.bintray.com/dev-fingerlinks/maven'
        }
        mavenCentral()
    }
}

You can also pipe commands inside Docker container, bash -c "<command1> | <command2>" for example:

docker run img /bin/bash -c "ls -1 | wc -l"

But, without invoking the shell in the remote the output will be redirected to the local terminal.

You have already found NSDateFormatter, just read the documentation on it.

The way you're doing it you're querying for the process twice. Also Lynn raises a good point about being nice first. I'd probably try something like the following:

# get Firefox process
$firefox = Get-Process firefox -ErrorAction SilentlyContinue
if ($firefox) {
  # try gracefully first
  $firefox.CloseMainWindow()
  # kill after five seconds
  Sleep 5
  if (!$firefox.HasExited) {
    $firefox | Stop-Process -Force
  }
}
Remove-Variable firefox

maybe this help :

declare 
@statement AS NVARCHAR(MAX)
,@text1 varchar(50)='hello'
,@text2 varchar(50)='world'

set @statement = '
select '''+@text1+''' + '' beautifull '' + ''' + @text2 + ''' 
'
exec sp_executesql @statement;

this is same as below :

select @text1 + ' beautifull ' + @text2

In your doSomething() function, pass in the event e and use e.preventDefault().

doSomething = function (e) {
    alert('it works!');
    e.preventDefault();
}

You have to increase client_max_body_size in nginx.conf file. This is the basic step. But if your backend laravel then you have to do some changes in the php.ini file as well. It depends on your backend. Below I mentioned file location and condition name.

sudo vim /etc/nginx/nginx.conf.

After open the file adds this into HTTP section.

client_max_body_size 100M;

Set self.title = "" before self.navigationController?.pushViewController(vc, animated: true).

You are mixing razor and aspx syntax,if your view engine is razor just do this:

<button class="btn btn-info" type="button" id="addressSearch"   
          onclick="location.href='@Url.Action("List", "Search")'">

Run composer install in your root project folder (or php composer.phar install).

Or, as inspired by @MatheusAraujo:

df[nrow(df) + 1,] = list("v1","v2")

This would allow for mixed data types.

For me, the problem was trying to pass a filename in a url, with a dot. For example

"http://localhost:8080/something/asdf.jpg" //causes error because of '.jpg'

It could be solved by not passing the .jpg extension, or sending it all in a request body.

The correct (lldb) command is: Realm.Configuration.defaultConfiguration.path.

=INDIRECT("'C:\Data["&A8&"]SheetNAME'!$G9")

where A8 contains myExcelFile.xlsm

and G9 contains your source workbook precious data.

recyclerView.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.HORIZONTAL,false));

recyclerView.setAdapter(adapter);

One additional information I just one to add is that a PATCH request use less bandwidth compared to a PUT request since just a part of the data is sent not the whole entity. So just use a PATCH request for updates of specific records like (1-3 records) while PUT request for updating a larger amount of data. That is it, don't think too much or worry about it too much.

For those who are still getting blank response with $request->getContent(), you can use:

$request->all()

e.g:

public function foo(Request $request){
   $bodyContent = $request->all();
}

You may use display:table/table-cell;

.a{_x000D_
   position: absolute; _x000D_
  left: 50px; _x000D_
  top: 50px;_x000D_
  display:table;_x000D_
}_x000D_
.b{_x000D_
  text-align: left; _x000D_
  display:table-cell;_x000D_
  height: 56px;_x000D_
  vertical-align: middle;_x000D_
  background-color: pink;_x000D_
}_x000D_
.c {_x000D_
  background-color: lightblue;_x000D_
}

<div class="a">_x000D_
  <div  class="b">_x000D_
    <div class="c" >test</div>_x000D_
  </div>_x000D_
</div>

You need to switch single quotes ['] to double quotes ["] because of parse

if you are using data-order attribute on the table then use it like this data-order='[[1, "asc"]]'

It is ES-6 feature. It means you extract all the properties of props in div.{... }

operator is used to extract properties of an object.

CSS:

.headercss {
    width: 100%;
    height: 320px;
    background-color: #000000;
    position: fixed;
}

Attribute position: fixed will keep it stuck, while other content will be scrollable. Don't forget to set width:100% to make it fill fully to the right.

Example

I was facing the same problem. I have deleted the target folder and run maven install, it worked.

Correct, when you drag a view controller object onto your storyboard in order to create a new scene, it doesn't automatically make the new class for you, too.

Having added a new view controller scene to your storyboard, you then have to:

1. Create a UIViewController subclass. For example, go to your target's folder in the project navigator panel on the left and then control-click and choose "New File...". Choose a "Cocoa Touch Class":

   

   And then select a unique name for the new view controller subclass:

   

2. Specify this new subclass as the base class for the scene you just added to the storyboard.

   

3. Now hook up any IBOutlet and IBAction references for this new scene with the new view controller subclass.

From the fine manual.

You must own the table to use ALTER TABLE.

Or be a database superuser.

ERROR: must be owner of relation contact

PostgreSQL error messages are usually spot on. This one is spot on.

Your encoded text is [B@6499375d. That is not Base64, something went wrong while encoding. That decoding code looks good.

Use this code to convert the byte[] to a String before adding it to the URL:

String encodedEmailString = new String(encodedEmail, "UTF-8");
// ...
String confirmLink = "Complete your registration by clicking on following"
    + "\n<a href='" + confirmationURL + encodedEmailString + "'>link</a>";

If you land here using jwt authentication after the PyJWT v2.0.0 release (22/12/2020), you might want to freeze your version of PyJWT to the previous release in your requirements.txt file.

PyJWT==1.7.1

I have met the same problem. My project is running on the local server. I checked my php code.

$db = mysqli_connect('localhost', 'root', 'root', 'smart');

I use localhost to connect to my local database. That maybe the cause of the problem which you're describing. You can modify your HOSTS file. Add the line

127.0.0.1 localhost.

The only way that comes to mind for this from a consumer point of view is to actually consume the messages and count them then.

The Kafka broker exposes JMX counters for number of messages received since start-up but you cannot know how many of them have been purged already.

In most common scenarios, messages in Kafka is best seen as an infinite stream and getting a discrete value of how many that is currently being kept on disk is not relevant. Furthermore things get more complicated when dealing with a cluster of brokers which all have a subset of the messages in a topic.

Try this :

<?php
    global $woocommerce;
    $items = $woocommerce->cart->get_cart();

        foreach($items as $item => $values) { 
            $_product =  wc_get_product( $values['data']->get_id()); 
            echo "<b>".$_product->get_title().'</b>  <br> Quantity: '.$values['quantity'].'<br>'; 
            $price = get_post_meta($values['product_id'] , '_price', true);
            echo "  Price: ".$price."<br>";
        } 
?>

To get Product Image and Regular & Sale Price:

<?php
    global $woocommerce;
    $items = $woocommerce->cart->get_cart();

        foreach($items as $item => $values) { 
            $_product =  wc_get_product( $values['data']->get_id() );
            //product image
            $getProductDetail = wc_get_product( $values['product_id'] );
            echo $getProductDetail->get_image(); // accepts 2 arguments ( size, attr )

            echo "<b>".$_product->get_title() .'</b>  <br> Quantity: '.$values['quantity'].'<br>'; 
            $price = get_post_meta($values['product_id'] , '_price', true);
            echo "  Price: ".$price."<br>";
            /*Regular Price and Sale Price*/
            echo "Regular Price: ".get_post_meta($values['product_id'] , '_regular_price', true)."<br>";
            echo "Sale Price: ".get_post_meta($values['product_id'] , '_sale_price', true)."<br>";
        }
?>

also it happens when you import following library to api.php file. this happens by some IDE's suggestion to import it for not finding the Route Class.

just remove it and everything going to work fine.

use Illuminate\Routing\Route;

update:

seems if you add this library it wont lead to error

use Illuminate\Support\Facades\Route;

Tested with: log4j-ap 2.13.2, log4j-core 2.13.2.

1. Keep XML file directly under below folder structure. src/main/java
2. In the POM:

    <build>   
 <resources>       
             <resource>
                <filtering>false</filtering>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>             
            </resource>
 </resources>  
</build>

3. Clean and build.

You can also try using parameters directive for making your build parameterized and accessing parameters:

Doc: Pipeline syntax: Parameters

Example:

pipeline{

agent { node { label 'test' } }
options { skipDefaultCheckout() }

parameters {
    string(name: 'suiteFile', defaultValue: '', description: 'Suite File')
}
stages{

    stage('Initialize'){

        steps{

          echo "${params.suiteFile}"

        }
    }
 }

Swift 3 version of BadmintonCat's answer

extension String {
    func replace(_ string:String, replacement:String) -> String {
        return self.replacingOccurrences(of: string, with: replacement, options: NSString.CompareOptions.literal, range: nil)
    }

    func removeWhitespace() -> String {
        return self.replace(" ", replacement: "")
    }
}

You need to make use of Label Callback. A common example to round data values, the following example rounds the data to two decimal places.

var chart = new Chart(ctx, {
    type: 'line',
    data: data,
    options: {
        tooltips: {
            callbacks: {
                label: function(tooltipItem, data) {
                    var label = data.datasets[tooltipItem.datasetIndex].label || '';

                    if (label) {
                        label += ': ';
                    }
                    label += Math.round(tooltipItem.yLabel * 100) / 100;
                    return label;
                }
            }
        }
    }
});

Now let me write the scenario where I used the label callback functionality.

Let's start with logging the arguments of Label Callback function, you will see structure similar to this here datasets, array comprises of different lines you want to plot in the chart. In my case it's 4, that's why length of datasets array is 4.

In my case, I had to perform some calculations on each dataset and have to identify the correct line, every-time I hover upon a line in a chart.

To differentiate different lines and manipulate the data of hovered tooltip based on the data of other lines I had to write this logic.

  callbacks: {
    label: function (tooltipItem, data) {
      console.log('data', data);
      console.log('tooltipItem', tooltipItem);
      let updatedToolTip: number;
      if (tooltipItem.datasetIndex == 0) {
        updatedToolTip = tooltipItem.yLabel;
      }
      if (tooltipItem.datasetIndex == 1) {
        updatedToolTip = tooltipItem.yLabel - data.datasets[0].data[tooltipItem.index];
      }
      if (tooltipItem.datasetIndex == 2) {
        updatedToolTip = tooltipItem.yLabel - data.datasets[1].data[tooltipItem.index];
      }
      if (tooltipItem.datasetIndex == 3) {
        updatedToolTip = tooltipItem.yLabel - data.datasets[2].data[tooltipItem.index]
      }
      return updatedToolTip;
    }
  } 

Above mentioned scenario will come handy, when you have to plot different lines in line-chart and manipulate tooltip of the hovered point of a line, based on the data of other point belonging to different line in the chart at the same index.

For me, it worked when I selected the correct bit of my Python version, NOT the one of my computer version.

Mine is 32bit, and my computer is 64bit. That was the problem and the 32bit version of fixed it.

To be exact, here is the one that I downloaded and worked for me:

mysqlclient-1.3.13-cp37-cp37m-win32.whl

Once again, just make sure to chose your python version of bits and not your system one.

There are so many ways to do this, here is some more:

string.Join(Environment.NewLine, dictionary.Select(a => $"{a.Key}: {a.Value}"))

dictionary.Select(a => $"{a.Key}: {a.Value}{Environment.NewLine}")).Aggregate((a,b)=>a+b)

new String(dictionary.SelectMany(a => $"{a.Key}: {a.Value} {Environment.NewLine}").ToArray())

Additionally, you can then use one of these and encapsulate it in an extension method:

public static class DictionaryExtensions
{
    public static string ToReadable<T,V>(this Dictionary<T, V> d){
        return string.Join(Environment.NewLine, d.Select(a => $"{a.Key}: {a.Value}"));
    }   
}

And use it like this: yourDictionary.ToReadable().

Database table

Having the following blog database table storing the blogs hosted by our platform:

And, we have two blogs currently hosted:

Getting our report without using the SQL LATERAL JOIN

We need to build a report that extracts the following data from the blog table:

• the blog id
• the blog age, in years
• the date for the next blog anniversary
• the number of days remaining until the next anniversary.

If you're using PostgreSQL, then you have to execute the following SQL query:

SELECT
  b.id as blog_id,
  extract(
    YEAR FROM age(now(), b.created_on)
  ) AS age_in_years,
  date(
    created_on + (
      extract(YEAR FROM age(now(), b.created_on)) + 1
    ) * interval '1 year'
  ) AS next_anniversary,
  date(
    created_on + (
      extract(YEAR FROM age(now(), b.created_on)) + 1
    ) * interval '1 year'
  ) - date(now()) AS days_to_next_anniversary
FROM blog b
ORDER BY blog_id

As you can see, the age_in_years has to be defined three times because you need it when calculating the next_anniversary and days_to_next_anniversary values.

And, that's exactly where LATERAL JOIN can help us.

Getting the report using the SQL LATERAL JOIN

The following relational database systems support the LATERAL JOIN syntax:

• Oracle since 12c
• PostgreSQL since 9.3
• MySQL since 8.0.14

SQL Server can emulate the LATERAL JOIN using CROSS APPLY and OUTER APPLY.

LATERAL JOIN allows us to reuse the age_in_years value and just pass it further when calculating the next_anniversary and days_to_next_anniversary values.

The previous query can be rewritten to use the LATERAL JOIN, as follows:

SELECT
  b.id as blog_id,
  age_in_years,
  date(
    created_on + (age_in_years + 1) * interval '1 year'
  ) AS next_anniversary,
  date(
    created_on + (age_in_years + 1) * interval '1 year'
  ) - date(now()) AS days_to_next_anniversary
FROM blog b
CROSS JOIN LATERAL (
  SELECT
    cast(
      extract(YEAR FROM age(now(), b.created_on)) AS int
    ) AS age_in_years
) AS t
ORDER BY blog_id

And, the age_in_years value can be calculated one and reused for the next_anniversary and days_to_next_anniversary computations:

Much better, right?

The age_in_years is calculated for every record of the blog table. So, it works like a correlated subquery, but the subquery records are joined with the primary table and, for this reason, we can reference the columns produced by the subquery.

You try the following ways to run the multiple python scripts:

  import os
  print "Starting script1"
  os.system("python script1.py arg1 arg2 arg3")
  print "script1 ended"
  print "Starting script2"
  os.system("python script2.py arg1 arg2 arg3")
  print "script2 ended"

Note: The execution of multiple scripts depends purely underlined operating system, and it won't be concurrent, I was new comer in Python when I answered it.

Update: I found a package: https://pypi.org/project/schedule/ Above package can be used to run multiple scripts and function, please check this and maybe on weekend will provide some example too.

i.e:

 import schedule
 import time
 import script1, script2

 def job():
     print("I'm working...")

 schedule.every(10).minutes.do(job)
 schedule.every().hour.do(job)
 schedule.every().day.at("10:30").do(job)
 schedule.every(5).to(10).days.do(job)
 schedule.every().monday.do(job)
 schedule.every().wednesday.at("13:15").do(job)

 while True:
     schedule.run_pending()
     time.sleep(1)

Arrays in Java have a fixed length that cannot be changed. So Java provides classes that allow you to maintain lists of variable length.

Generally, there is the List<T> interface, which represents a list of instances of the class T. The easiest and most widely used implementation is the ArrayList. Here is an example:

List<String> words = new ArrayList<String>();
words.add("Hello");
words.add("World");
words.add("!");

List.add() simply appends an element to the list and you can get the size of a list using List.size().

Just add below annotation with qualifier name of service in service Implementation class:

@Service("employeeService")
@Transactional
public class EmployeeServiceImpl implements EmployeeService{
}

Chrome doesn't allow you to integrate two different localhost,that's why we are getting this error. You just have to include Microsoft Visual Studio Web Api Core package from nuget manager.And add the two lines of code in WebApi project's in your WebApiConfig.cs file.

var cors = new EnableCorsAttribute("*", "*", "*");
config.EnableCors(cors);

Then all done.

Adding to Ophirs answer, JsonFormat is available even before protobuf 3.0. However, the way to do it differs a little bit.

In Protobuf 3.0+, the JsonFormat class is a singleton and therefore do something like the below

String jsonString = "";
JsonFormat.parser().ignoringUnknownFields().merge(jsonString,yourObjectBuilder);

In Protobuf 2.5+, the below should work

String jsonString = "";
JsonFormat jsonFormat = new JsonFormat();
jsonString = jsonFormat.printToString(yourProtobufMessage);

Here is a link to a tutorial I wrote that uses the JsonFormat class in a TypeAdapter that can be registered to a GsonBuilder object. You can then use Gson's toJson and fromJson methods to convert the proto data to Java and back.

Replying to jean . If we have the protobuf data in a file and want to parse it into a protobuf message object, use the merge method TextFormat class. See the below snippet:

// Let your proto text data be in a file MessageDataAsProto.prototxt
// Read it into string  
String protoDataAsString = FileUtils.readFileToString(new File("MessageDataAsProto.prototxt"));

// Create an object of the message builder
MyMessage.Builder myMsgBuilder = MyMessage.newBuilder();

// Use text format to parse the data into the message builder
TextFormat.merge(protoDataAsString, ExtensionRegistry.getEmptyRegistry(), myMsgBuilder);

// Build the message and return
return myMsgBuilder.build();

To create a group of inputs you can create a custom html element

window.customElements.define('radio-group', RadioGroup);

https://gist.github.com/robdodson/85deb2f821f9beb2ed1ce049f6a6ed47

to keep selected option in each group, you need to add name attribute to inputs in group, if you not add it then all is one group.

Here is my sample how I use it. For the css/less task. Can be applied for all.

var cssTask = function (options) {
  var minifyCSS = require('gulp-minify-css'),
    less = require('gulp-less'),
    src = cssDependencies;

  src.push(codePath + '**/*.less');

  var run = function () {
    var start = Date.now();

    console.log('Start building CSS/LESS bundle');

    gulp.src(src)
      .pipe(gulpif(options.devBuild, plumber({
        errorHandler: onError
      })))
      .pipe(concat('main.css'))
      .pipe(less())
      .pipe(gulpif(options.minify, minifyCSS()))
      .pipe(gulp.dest(buildPath + 'css'))
      .pipe(gulpif(options.devBuild, browserSync.reload({stream:true})))
      .pipe(notify(function () {
        console.log('END CSS/LESS built in ' + (Date.now() - start) + 'ms');
      }));
  };

  run();

  if (options.watch) {
    gulp.watch(src, run);
  }
};

gulp.task('dev', function () {
  var options = {
    devBuild: true,
    minify: false,
    watch: false
  };

  cssTask (options);
});

I finally managed to create a query that does exactly what i wanted to have:

A filtered nested boolean query. I am not sure why this is not documented. Maybe someone here can tell me?

Here is the query:

GET /test/object/_search
{
  "from": 0,
  "size": 20,
  "sort": {
    "_score": "desc"
  },
  "query": {
    "filtered": {
      "filter": {
        "bool": {
          "must": [
            {
              "term": {
                "state": 1
              }
            }
          ]
        }
      },
      "query": {
        "bool": {
          "should": [
            {
              "bool": {
                "must": [
                  {
                    "match": {
                      "name": "foo"
                    }
                  },
                  {
                    "match": {
                      "name": "bar"
                    }
                  }
                ],
                "should": [
                  {
                    "match": {
                      "has_image": {
                        "query": 1,
                        "boost": 100
                      }
                    }
                  }
                ]
              }
            },
            {
              "bool": {
                "must": [
                  {
                    "match": {
                      "info": "foo"
                    }
                  },
                  {
                    "match": {
                      "info": "bar"
                    }
                  }
                ],
                "should": [
                  {
                    "match": {
                      "has_image": {
                        "query": 1,
                        "boost": 100
                      }
                    }
                  }
                ]
              }
            }
          ],
          "minimum_should_match": 1
        }
      }    
    }
  }
}

In pseudo-SQL:

SELECT * FROM /test/object
WHERE 
    ((name=foo AND name=bar) OR (info=foo AND info=bar))
AND state=1

Please keep in mind that it depends on your document field analysis and mappings how name=foo is internally handled. This can vary from a fuzzy to strict behavior.

"minimum_should_match": 1 says, that at least one of the should statements must be true.

This statements means that whenever there is a document in the resultset that contains has_image:1 it is boosted by factor 100. This changes result ordering.

"should": [
  {
    "match": {
      "has_image": {
        "query": 1,
        "boost": 100
      }
    }
   }
 ]

Have fun guys :)
